text: "Background\r\nPhotosynthetic cyanobacteria are attractive for a range of
biotechnological applications including biofuel production. However, due to slow
growth, screening of mutant libraries using microtiter plates is not feasible.\r\nResults\r\nWe
present a method for high-throughput, single-cell analysis and sorting of genetically
engineered l-lactate-producing strains of Synechocystis sp. PCC6803. A microfluidic
device is used to encapsulate single cells in picoliter droplets, assay the droplets
for l-lactate production, and sort strains with high productivity. We demonstrate
the separation of low- and high-producing reference strains, as well as enrichment
of a more productive l-lactate-synthesizing population after UV-induced mutagenesis.
The droplet platform also revealed population heterogeneity in photosynthetic
growth and lactate production, as well as the presence of metabolically stalled
cells.\r\nConclusions\r\nThe workflow will facilitate metabolic engineering and
directed evolution studies and will be useful in studies of cyanobacteria biochemistry
and physiology.\r\n"
